    I was told that these make FMS worse. Tomatos, potatoes are night shade vegetables. I have been eating my weight in tomatos all summer and have really have been sick. This person I talked to today said when she stopped them, she felt so much better. Let me know what you know. Thanks.

    these foods make arthritis worse, but I had not heard about FM and these foods. Since many who have FM have arthritis, also, I guess it might be a good idea to limit these. Sorry you had such a bad summer!

    Where did your friend read this information? I'd be interested to know the source.

    Thanks for posting this!

    Extract from Nightshade foods by Craig Sams

    In the diet of Europe and Asia, only one nightshade food was eaten until recent times: the aubergine or eggplant. Other nightshades such as henbane, thorn apple (datura stramonium), belladonna and mandrake were well known but their use was restricted to specific medical applications (sedative, anesthetic or poison) or in witchcraft.

    Then, in the 1600s and 1700s food and drug crops based on nightshades were imported from the Americas and for the past 400 years have penetrated and become ubiquitous in the Western diet. These include tobacco, tomatoes, potatoes and chili peppers.

    It is not surprising that these novel foods, being nightshades, were regarded with suspicion at first and were slow to take hold in the European diet. They all contain nicotine in some form, although it may be named solanine (potatoes), tomatine (tomatoes), alpha-solanine (aubergine) or solanadine (chillies and capsicums).

    It is now apparent that there are groups of people who cannot tolerate nightshades in their diets, wish to avoid them anyway or find that eliminating them helps alleviate a variety of mental, emotional and physical problems. The following groups of people avoid nightshades.

    People with arthritis

    Some researchers believe that arthritis is misdiagnosed in people who are in fact just suffering joint aches and swelling arising from consumption of nightshades. One in three arthritics react badly to nightshades. These individuals frequently have a sensitivity to the solanine chemicals present in these foods. It can take up to six months of exclusion of nightshades from the diet to achieve a beneficial effect.

    Macrobiotics

    since the 1960s, the macrobiotic diet has recommended avoidance of all nightshades. This proven diet for health and longevity is followed by celebrities such as Sadie Frost, Gwyneth Paltrow, Chris Martin of Coldplay and Madonna.

    Children with eczema

    for some children the elimination of nightshades from the diet helps clear eczema, particularly around the mouth.
    Gastro Esophogal Reflux disease - consumption of nightshade vegetables, particularly tomatoes, can causes a reaction where the stomach contents are pushed back up the esophagus towards the throat with symptoms of heartburn, chest pain, choking while lying down and asthma symptoms when sleeping.

    Those quitting smoking

    some programmes to help people give up cigarettes also recommend giving up nightshade foods in order to completely eliminate low level nicotine intake and consequent re-addiction.

    Blood group diet

    Dr. Peter d'Adamo's Blood Type Diet recommends people of blood types A and B to avoid all nightshade foods. This represents about half the population of most European countries.

    Cystitis, lupus, psoriasis

    giving up nightshades can help relieve symptoms of cystitis, lupus and psoriasis.


    What are the Nightshade foods? How do they differ from each other? What are their origins?

    Tobacco

    The most powerful source of the nicotine alkaloid found in all nightshades became a popular drug in the early part of the 1900s, when mass produced cigarettes made them available to the expanding urban societies.

    Although the nicotine content of tobacco is much higher than that found in nightshade vegetables which are eaten, the practise of smoking reduces the amount of nicotine absorbed. The nicotine in a single cigarette, if taken direct into the bloodstream, would be fatal. Eating a single cigarette could cause severe illness. There are several instances of livestock poisoning where cattle or sheep have eaten nightshade plant leaves.

    Tomatoes

    Tomatoes were first brought to Europe from Mexico by Cortez and were first cultivated for food in Naples. The English regarded them as poisonous until the 1700s. They were introduced in America as an ornamental garden plant in 1808, but were not eaten as they were believed to cause stomach cancer and appendicitis.

    The botanical name for tomatoes 'Lycopersicon' means 'wolf peach' and refers to the association between werewolves, witchcraft and nightshades. Then, in 1820, Colonel Robert Johnson defied the advice of his physicians ("You will foam and froth at the mouth and double over") and ate tomatoes on the steps of Salem Courthouse, New Jersey, in front of a crowd of 2000 witnesses, the local sheriff waiting to arrest him for suicide. He survived and people began slowly to accept tomatoes as food.

    In the US and Northern Europe they really took off as food with the introduction of canning and canned soups and then rose again with the expansion of consumption of pizza and pasta in the past 30 years.

    Potatoes

    Potatoes were elevated in status when the celebrated Parmentier produced a galaxy of delicious potato recipes in 1785 to help relieve famine in Paris. Potatoes were cheap food for the masses - a peasant or worker could be fed from a quarter as much land if they ate potatoes instead of grain. Nonetheless, the French Revolution took place 4 years later. The Paris Commune declared potatoes 'Revolutionary food' while English landlords made them compulsory on their Irish estates.

    Traditionally potatoes were kept in paper sacks and sold unwashed. This practice protected them from direct sunlight. The modern practice of washing potatoes and packing them in plastic bags allows light to affect the potato and stimulate its production of solanine, the nightshade alkaloid that, in nature, sickens animals that might dig up potatoes for food.

    In 1976 the Department of Health, concerned about high levels of anencephaly and spina bifida, urged pregnant mothers to wear rubber gloves when preparing potatoes and to discard in their entirety any potatoes that showed signs of greening or of blight (black streaks in the potato). It is not enough to simply remove the discoloured part - the entire potato should not be eaten.

    The solanine in potatoes is 4 times greater in the skin than in the rest of the potato. The fatal dose of solanine for an adult is 200-250 mg depending on body weight.

    Potatoes should not contain more than 20 mg of solanine per 100g, so it would take at least 1 Kg of potatoes (2.2 lbs) to be fatal. Potato peels have been found to contain up to 180 mg of solanine per 100g, so a person consuming 150-200g of deep fried potato peels with a high solanine content could be at considerable risk. Potatoes that have been properly stored and are from low solanine varieties will only contain 7 mg/100g.

    In 1996 the Committee on Toxicity stated that potatoes should not be eaten if they still taste bitter after the green parts and sprouts have been removed. However, few people taste-test a raw potato once it is peeled to assess its bitterness.

    Although spina bifida prevention now focuses on preconceptual consumption of folic acid, the world's highest incidence of spina bifida is in Ireland, where the wet climate encourages late potato blight. A study in Belfast showed that mothers who had given birth to a child with spina bifida or anencephaly could reduce the risk of a similar defect in the second child by 50% if they maintained a potato-free diet.

    Peppers and capsicums

    Peppers and capsicums were rare in the Western diet until the 1980s, when they became widely available as fresh vegetables and, in their hotter forms, in Asian cuisine and as hot sauce. Chillis replaced peppercorns in Indian cuisine from the 1650s onwards, after Portuguese traders brought plants and seeds from Brazil.

    Hot peppers are rich in capsaicin, which creates a burning sensation that affects pain receptor cells and causes them to release endorphins, the body's natural opiate-like painkillers, that create a temporary feeling of euphoria.

    Peppers and capsicums also contain solanine and solanadine, the nicotine compounds that are unique to nightshade plants.

    Aubergines

    Aubergines or eggplants most resemble in appearance the belladonna nightshade plant that may be their wild ancestor.

    ------------

    So what is nicotine (solanine), the active alkaloid in nightshades? What are its effects? Nicotine acts as an acetylcholinesterase inhibitor.

    What are acetylcholinesterase inhibitors?

    The chemical that transmits nerve impulses from one nerve ending to the next is acetylcholine - once it has transmitted a nerve impulse it has done its job and is no longer needed so it is broken down by an enzyme called acetylcholinesterase and recycled.

    Nictotine/Solanine (or tomatine from tomatoes) slows the production of this acetylcholinesterase, so acetylcholine isn't broken down as fast as it's being produced.
    Acetylcholine builds up causing a 'traffic jam' of stimulation at the receptor nerve endings. Or think of an orchestra where notes are played and then don't stop playing.

    The nerve endings become overstimulated. At low levels this is mildly pleasurable and blurs sensitivity, but too much can be harmful.

    This overstimulation can lead to muscle weakness, muscle twitching, hypertension, increased intestinal contractions and increased secretions of tear, sweat, saliva, gastric and intestinal glands.

    All nightshade foods contain solanine, a strong acetylcholinesterase inhibitor. This is what makes excessive consumption of nightshade foods unsuitable for many people.

    Certain pesticides, particularly organophosphate and carbamates, also work as acetylcholinesterase inhibitors, achieving the same effect as solanine or nicotine. That's why they replaced nicotine as the insecticide of choice after World War 2, when organophosphates were used as nerve gas.

    For a diet that seeks to maintain a strong and healthy nervous and neuromuscular system there is considerable evidence that the safest approach is to avoid nightshade vegetables and to eat food that is grown without the use of carbamate or organophosphate pesticides, i.e. organic food.

    Before the discovery of chemical pesticides, nicotine was a widely used insecticide. It kills insects in the same way, but chemical sprays are cheaper and longer-lasting. Until they were replaced by hormones and antibiotics, organophosphate pesticides were also used by livestock farmers as growth-promoters - the mechanism whereby they cause muscle weakness and increase secretions of digestive fluids also causes animals to exercise less and eat more, thereby fattening them up more quickly.[This Message was Edited on 10/16/2005]

    While i've given up nightshade plants for periods of time with no noticeable changes...

    My Dad couldn't eat raw tomatoes as he'd found on his own that his knees would ache. Yet for some reason he could eat them cooked.

    BUT he certainly ate the rest of the family of nightshades and smoked without any aches... very strange!
